Millions of people use mobile phone banking daily, and business leaders should understand the factors influencing mobile phone banking adoption among users. Based on the theory of technology acceptance model and the innovation diffusion theory, the purpose of this correlational study was to examine the relationship between usefulness, ease of use, risk, cost, and mobile phone banking adoption in Burkina Faso. One hundred and six mobile phone banking users living in the city of Ouagadougou completed the online survey created to measure consumers understanding of mobile phone banking. Results of the multiple linear regression analysis indicated a statistically significant relationship between the predictor variables and mobile phone banking adoption, F(5,101) = 36.07, p < .001. Three of the predictors contributed significantly to the model, with usefulness recording the highest beta value (Ã? = .692), cost the next highest beta value (Ã? = .225), and ease of use the next highest beta value (Ã? = .173). The 4th predictor, risk, did not contribute significantly to the model, recording a negative beta value (Ã? = -.058). Results may enhance local business leaders' understanding of mobile phone banking adoption, which could result in more effective business strategies to increase the affordability, availability, and quality of mobile banking services for Burkina Faso residents. Development of the mobile phone banking industry could enable business leaders to foster access to affordable financial services for individuals and contribute to the development of Burkina Faso's local economy and trade.

Indiana University-Purdue University Indianapolis (IUPUI) / Background: Pulmonary rehabilitation (PR) has the potential to reduce the symptoms and complications of respiratory diseases through an interdisciplinary approach. Providing PR services to the increasing number of patients with chronic respiratory diseases challenges the current health care systems because of the shortages in health care practitioners and PR programs. Using telerehabilitation may improve patients’ participation and compliance with PR programs. The purpose of this study was to examine the applicability of the technology acceptance model (TAM) to explain telerehabilitation acceptance and to determine the demographic variables that can influence acceptance. Methods: A cross-sectional survey-based design was utilized in the data collection. The survey scales were based on the TAM. The first group of participants consisted of health care practitioners working in PR programs. The second group of participants included patients attending traditional PR programs. The data collection process started in January 2017 and lasted until May 2017. Results: A total of 222 health care practitioners and 134 patients completed the survey. The results showed that 79% of the health care practitioners and 61.2% of the patients reported positive intention to use telerehabilitation. Regression analyses showed that the TAM was good at predicting telerehabilitation acceptance. Perceived usefulness was a significant predictor of the positive intentions to use telerehabilitation for health care providers (OR: 17.81, p < .01) and for the patients (OR: 6.46, p = .04). The logistic regression outcomes showed that age, experience in rehabilitation, and type of PR increased the power of the TAM to predict the intention to use telerehabilitation among health care practitioners. Age, duration of the disease, and distance from the PR center increased the power of the TAM to predict the intention to use telerehabilitation among patients. Conclusion: This is the first study to develop and validate a psychometric instrument to measure telerehabilitation acceptance among health care practitioners and patients in PR programs. The outcomes of this study will help in understanding the telerehabilitation acceptance. It will help not only to predict future adoption but also to develop appropriate solutions to address the barriers of using telerehabilitation.

Indiana University-Purdue University Indianapolis (IUPUI) / Medication nonadherence among middle-aged to older adults with chronic conditions often stems from forgetting to take or fill medications as prescribed. A pilot study indicated the feasibility of technology acceptance model (TAM)-based smartphone medication reminder app (SMRA) training as a way to promote their app use and medication adherence. This dissertation assesses the viability and effect size of the modified TAM-based SMRA training in promoting app use and medication adherence, as well as its delivery design in preparation for a larger efficacy study. A two-group pretest-posttest design was employed. Twenty-nine adults aged over 40 years and taking medications for chronic condition management were recruited from Midwestern university and community sites. The training group (n = 15) received the modified TAM-based SMRA training; whereas the non-training group (n = 14) self-navigated app features. The training group reported significantly higher levels of perceived usefulness, perceived ease of use, positive subjective norm, and intention to use the app. In addition, the training group reported a higher proportion of active app use than the non-training group. Modified TAM-based SMRA training was not viable in increasing the levels of medication adherence variables. Effect sizes suggested at least 52 participants as a sample size for a larger efficacy study. Participants suggested that training could be improved by scheduling separate group training for iPhone and Android phone users, providing a live online training option, providing small group training with peer helper, tailoring training length to participant preference, and working with family members and healthcare providers as co-trainees and co-trainers.

Background: The emerging cryptocurrency market becomes more and more recognized around the globe. Therefore, it has become of great interest to policymakers, institutional investors, and individual investors. The new encrypted blockchain technology offers individual investors contemporary opportunities to invest contrary to traditional means. However, the volatile market presents instabilities and uncertainty for market participants creating a research gap for academics to investigate what poses these difficulties.  Purpose: The objective of the study is to investigate the determinants that affect individual investors' adoption intention of Bitcoin. By incorporating theories to understand investment behaviors and attitudes.  Methodology: The thesis utilized a quantitative methodology and collected data through an online questionnaire with the help of a Likert-scale instrument. The survey participants ended with a number of 114 respondents that are characterized as young adult investors. Interpretation and evaluation of the results were analyzed through an OLS linear regression with the help of a software program, Minitab.  Findings: Theresearchquestionwasansweredtoasatisfactorylevel,whereresultsattested to past works of literatures. The study found that consumer characteristic is a driving cause for individual investors' adoption intention of Bitcoin. To elaborate, subjective norms of individuals navigate their attitude towards Bitcoin, and investors’ peers’ opinions and acceptance play a crucial role in their engagement in the market. The herding trend was the most significant variable that contributed to investors’ adoption intention. The results also showed a significant correlation toward the technology acceptance model. Nonetheless, the study lacked empirical evidence to support market characteristics steering private investors’ adoption intention.  Implications &amp; Future Research suggestions: The main implications of the study were factors that regarded data collection and methods. Due to a time limitation, the survey was not available for a longer period of time, a longitudinal study could be of interest whilst incorporating more consumer characteristics into the analysis. In addition, future scholars ought to focus on market characteristics and how they influence varying cryptocurrencies such as Ethereum and Tether alongside Bitcoin. To conclude, a larger scope of the study could bring about more significant results and interesting findings.

The purpose of this study was to determine if the Technology Acceptance Model (TAM) could explain the relationship between teacher's acceptance of an online teacher professional development course and their continuance intentions regarding online teacher professional development (oTPD). This study focused on the perceptions of the teachers as opposed to the design or implementation of oTPD. The participants (N=517) were mostly teachers (88.8%) enrolled in a statewide online course to provide classroom teachers with the latest knowledge of research-based instructional reading strategies. The course was offered over a 10-14 week period during the Spring 2006 semester through a public state university. Structural equation modeling was used to create a path analytic model extending the TAM to include two additional constructs: sociability and social presence. In addition, gains in instructional reading strategies knowledge (performance) were examined. Using this expanded version of the TAM, the study examined the causal relationships between sociability, social presence, perceived usefulness, perceived ease of use, continuance intention, and gains. Online distance education research has indicated that social presence can influence post-secondary students' attitude and persistence within a web-based course. However a paucity of research exists on how technology acceptance and social presence impacts teachers within an online teacher professional development setting. Path analysis, univariate analysis of variance, and independent t-tests in SPSS v12.0 for Windows were used to analyze the data. The results suggest that the hypothesized extended model was a good fit. The model did indicate that both perceived ease of use and perceived usefulness were determinants of teachers' intent to continue using oTPD for future professional development needs.

The purpose of this research study was to use the Technology Acceptance Model (Pan, 2003) for re-examination of the relationships between students' attitude toward the use of WebCT and the relevance of the actual usage in light of social presence and sociability. By using Technology Acceptance Model (TAM) developed by F. Davis (1989), this study focused on variables such as perceived usefulness, perceived ease of use, computer self-efficacy, subjective norms, attitude and actual use of WebCT to account for the effect towards the achievement in the exam which is an outcome variable. The data were collected over three different time periods during the spring semester of 2007 to find how these results changed over time. The participants were the students who enrolled in the business marketing course (Principle of marketing) at the University of Central Florida in spring, 2007. The course was divided to three sections: on-campus, video-streaming and online classes. Although there were three different delivery methods, there was only one instructor and they used same material for all sections so the results were used to compare the differences from three classes. The study was conducted by using instruments to measure perceived usefulness, perceived ease of use, computer self-efficacy, subjective norms, actual use, attitude, sociability, social presence and an additional demographic instrument.

Social media is a fast growing platform when it comes to marketing. It is, however, used to a greater extent by business-to-consumer (B2C) companies than by business-to-business (B2B) companies. Because of this there has been considerably less research done concerning marketing on social media for B2B, compared to B2C.  This study explores why social media marketing is less common in B2B than B2C. This was done by conducting eleven one-on-one interviews with people who work at different B2B companies, and who have influence over their respective company’s marketing process. To analyse and evaluate the findings of this study the Technology Acceptance Model (TAM) was used. By identifying the external variables that deter B2B companies from using social media the perceived usefulness and ease of use were analysed in order to explore what affects the difference in social media acceptance for marketing between B2B and B2C companies.  The findings of this study show that the perceived ease of use is the dominant factor that deters B2B companies from using social media for marketing purposes. This is however not the reason for the difference between B2B and B2C. The difference can instead be explained by a more negative perception of the usefulness of marketing on social media. This negative perception is a result of the characteristics of social media, the industry the company is operating within, as well as the company’s products and customers. / Sociala medier är en snabbt växande plattform när det kommer till marknadsföring. Det används dock i större utsträckning av business-to-consumer (B2C) företag än av business-to-business (B2B) företag. På grund av detta har det gjorts betydligt mindre forskning gällande marknadsföring på sociala medier för B2B än vad som har gjorts för B2C. Denna studie utforskar varför marknadsföring på sociala medier är mindre vanligt i B2B än B2C. Detta har gjorts genom att genomföra 11 intervjuer, öga-mot-öga, med personer som arbetar på olika B2B-företag och som har inflytande över sitt respektive företags marknadsföringsprocess. För att analysera och utvärdera resultaten från denna studie användes Technology Acceptance Model (TAM), en modell som mäter acceptansen av olika tekniska plattformar. Genom att identifiera de externa variabler som hindrar B2B-företag från att använda sociala medier analyserades användbarheten och användarvänligheten, som den uppfattas av dem intervjuade, för att undersöka vad som påverkar skillnaden i sociala media acceptans i marknadsföringssyfte mellan B2C- och B2B-företag.  Resultaten av denna studie visar att den upplevda användarvänligheten är den dominerande faktorn som hindrar B2B-företag från att använda sociala medier för marknadsföringssyften. Detta är dock inte orsaken till skillnaden mellan B2B och B2C. Skillnaden kan istället förklaras av en negativare uppfattning av användbarheten av marknadsföring på sociala medier. Denna negativa uppfattning är ett resultat av egenskaperna hos sociala medier, den bransch som företaget är verksam inom, samt företagets produkter och kunder.

This study aims to investigate college students' security awareness of using social media in sharing information. The two theories that have guided this study are the theory of planned behavior (TPB) and the technology acceptance model (TAM). Data was collected from both undergraduate and graduate students from the University of North Texas (UNT) in Denton. The total responses included 380 students from different majors with 291 valid responses for data analysis; The structural equation model (SEM) Lavaan package was used to find out the best fit of the model. A diagonally weighted least squares (DWLS) was used to model the variables as ordinal in this study's analysis as ordinal data made the model fit substantially. The study found that 6 factors: attitude (AB), subjective norm (SN), perceived behavior control (PBC), perceived usefulness (PU), perceived risks (PR), and security awareness (SA) influenced behavior intention (BI). Also, I found that AB was influenced by PR and SA, as well as SN influenced by SA. Self-efficacy (SE) influenced PBC. On the other hand, the study found that controllability (C) did not influence PBC; perhaps, an individual's skills do not interact with social media security settings. Perceived ease of use (PEOU) did not influence BI; perhaps this occurred because of an individual's inability to prevent his or her information from being disclosed in the future, even if they had taken the right precautions. This study contributed to literature on understanding the nature of information sharing among college students on social media. The results may help college security professionals to evaluate or revise the rules and policies regarding cybersecurity and privacy.

Världen blir bara mer och mer digitaliserad där interaktionen med webbplatser är nästan oundviklig i dagens samhälle. För att göra webbplatser tillgängliga finns WCAG´s riktlinjer för att inkludera fler individer, med eller utan funktionsvariation. I dagsläget har cirka 5–8 procent av Europas befolkning diagnostiserats med dyslexi,vilket är en stor del att ta hänsyn till när det kommer till tillgänglighet. Det finns olika hjälpmedel för att underlätta dyslektikers utmaningar men i denna studie appliceras ett skärmläsarverktyg för att se om det kan hjälpa för att uppleva användbarhet. Idag finns det mycket forskning kring dyslexi, men det finns inte lika mycket forskning om just dyslektikers upplevelser kring hur skärmläsarverktyg påverkar användarupplevelsen. Syftet med studien var att undersöka dyslektikers användarupplevelser på webben ochom ett skärmläsarverktyg påverkar användarupplevelsen. Därför var målsättningen att undersöka de specifika utmaningar som dyslektiker har med hjälp av begrepp, ramverk och definitioner kring tillgänglighet. I studien har semistrukturerade intervjuer använts vilket är en kvalitativ datainsamlingsmetod. Totalt genomfördes åtta intervjuer med åtta personer som har dyslexi. För att samla in empiri från personer med dyslexi har en intervjuguide använts som bestått av 17 frågor samt följdfrågor på vardera fråga. För att analysera den insamlade data har transkribering, färgkodning och tematisering genomförts. I studien har det konstaterats att beroende på vilka utmaningar en person med dyslexi har är det individuellt hur de upplever webben. Beroende på vilka utmaningar ens dyslexi medför höjer eller sänker det användarupplevelsen på webben. De med mindre utmaningar tyckte att skärmläsarverktyget var för långsamt vid användning medan de med större utmaningar var mer beroende av det för att ta del av information och känna sig inkluderad i samhället. / The world is only becoming more and more digitized where interaction with websites is almost inevitable in today's society. To make websites accessible, there are WCAG's guidelines for including more individuals, with or without functional variation. Currently, approximately 5-8 percent of Europe's population has been diagnosed with dyslexia, which is a large proportion to take into account when it comes to accessibility. There are various aids to ease the challenges of dyslexics but in this study a screen reader tool is applied to see if it can help to experience usability. Today there is a lot of research on dyslexia, but there is not as much research on dyslexics' experiences of how screen reader tools affect the user experience. The aim of the study was to investigate the user experiences of dyslexics on the web and whether a screen reader tool affects the user experience. Therefore, the aim was to investigate the specific challenges that dyslexics have using concepts, frameworks and definitions around accessibility. In the study, semi-structured interviews were used, which is a qualitative data collection method. A total of eight interviews were conducted with eight people who have dyslexia. In order to collect empirical data from people with dyslexia, an interview guide was used which consisted of 17 questions and follow-up questions to each question. In order to analyze the collected data, transcription, color coding and thematization have been carried out. In the study, it was found that depending on the challenges a person with dyslexia has, it is individual how they experience the web. Depending on the challenges one's dyslexia brings, it raises or lowers the user experience on the web. Those with less challenges found the screen reader tool too slow to use, while those with greater challenges relied more on it to access information and feel included in the community.
